How to reach Vile Ted

Fast-travel to the Hydrus Sublab in the Terminus District of Dominion City and head east toward the facility. The encounter triggers during the side mission Below the Surface.

The fight: three targets, all with Vile Armor

“Vile Ted and the Experiments” is actually three enemies:

  • CorrupTed — a Mutant Psycho
  • Experiment 42 — a small Creep
  • Experiment 1709 — a large Creep

Each one is protected by Vile Armor sitting over a Flesh health bar. Strip the Vile Armor first, then punish the exposed flesh underneath. Bring an element you’re comfortable swapping to against flesh, and watch your spacing — you’re managing three threats at once rather than a single boss.

Drops

Vile Ted and the Experiments has two dedicated legendary drops:

  • Goalkeeper
  • Seventh Sense

In addition, the Red Chest after the encounter has a small chance to drop a random world-drop legendary, and it resets every time you respawn the boss — so the Moxxi’s Big Encore loop is worth running for both the dedicated drops and the chest rolls. Weapon types, elements and stats vary by drop, so confirm them in-game.
